suppose a bead maker wants to separate 10,000,000 beads into boxes she will put 100,000 beads into each box into which box would she put the 4,358,216th bead?

Looks like the question deals with rounding.

the first 43 boxes will hole 4,300,000 beads
so the 4,358,216 th bead will go in box # 44

PS, hope the bead maker does not pack them manually.
